Maxeon Solar Technologies Sues Canadian Solar for Patent Infringement over Tunnel Oxide Passivated Contact Technology

Maxeon Solar Technologies Begins Litigation Over TOPCon Patent Infringement

In the Eastern District of Texas, Maxeon Solar Technologies has filed a patent infringement lawsuit against Canadian Solar. The suit accuses Canadian Solar of violating Maxeon’s patents related to its tunnel oxide passivated contact (TOPCon) solar cell technology. Maxeon claims that their innovations in this field are protected by a global patent portfolio.

Marc Robinson, associate general counsel at Maxeon, stated that the company has a long history of developing solar cell technology and was among the first to commercialize tunnel oxide passivated contacts even before the term “TOPCon” became widely used in the industry. Maxeon holds numerous patents related to TOPCon technology, with inventions dating back to the 2000s. This lawsuit marks Maxeon’s first action to protect its valuable patent rights in the United States, and they intend to vigorously enforce these rights in other markets as well.

As a leader in solar energy innovation, Maxeon is committed to protecting its intellectual property and ensuring that its groundbreaking solar cell technologies are safeguarded. They will continue to take legal action to uphold their patents in order to maintain their position as a leader in the industry.
